Strikeforce’s swan song takes place Jan. 12 at Chesapeake Energy
Arena in Oklahoma City and will also feature Barnett’s most recent
opponent, unbeaten wrestler Daniel
Cormier, going up against Dutchman Dion
Staring.

Barnett dropped a five-round unanimous decision to Cormier in May’s
Strikeforce heavyweight grand prix final, snapping an eight-fight,
four-year unbeaten streak in the process. Since the dissolution of
Pride FC in 2008, Barnett has competed for several organizations --
including the short-lived Affliction and Japan’s Dream and Sengoku
promotions -- earning victories over such fellow veterans as
Pedro
Rizzo, Jeff Monson
and Sergei
Kharitonov.

With Strikeforce’s run coming to a end, it remains unknown whether
Barnett will be welcomed back to the UFC, where he has not competed
since 2002, when he was stripped of his heavyweight title after
testing positive for banned substances. Barnett tested positive for
anabolic steroids in 2009 prior to a scheduled bout with Fedor
Emelianenko in Anaheim, Calif., but in March was granted a
license to compete against Cormier by the California State Athletic
Commission.

Barnett’s opponent, 36-year-old Guelmino, will make his Strikeforce
debut on the heels of a seven-fight winning streak. The taekwondo
practitioner racked up three wins in 2012, most recently topping
Bulgarian standout Emil
Zahariev in an Oct. 21 unanimous decision.
